the river that feeds the Malheur is the donner and blitzen, or just blitzen. once they found the redbands, they shut it down, then reopened it to catch and release - I do not know current status. hiking up the gorge (access at last road crossing river) had great pocket water. big fish were lower down in the willow lined canal on the flats. garbage lid sized swirls. big time mosquitos. check the regs and if open, take your rod when you go birding out there.
